Make into improper fractions. Then make the denominators the same by finding the denominations' lowest common factor.
The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
Answer:
See below
Explanation:
vf = vo + at subtract vo from both sides
vf - vo = at now divide both sides by t
(vf-vo) / t = a
<span>Nuclear fission produces elements that are heavier than helium.
The elements that are used in nuclear fission and their products are much heavier than helium.</span>
Answer:
a) m = 993 g
b) E = 6.50 × 10¹⁴ J
Explanation:
atomic mass of hydrogen = 1.00794
4 hydrogen atom will make a helium atom = 4 × 1.00794 = 4.03176
we know atomic mass of helium = 4.002602
difference in the atomic mass of helium = 4.03176-4.002602 = 0.029158
fraction of mass lost = 
= 0.00723
loss of mass for 1000 g = 1000 × 0.00723 = 7.23
a) mass of helium produced = 1000-7.23 = 993 g (approx.)
b) energy released in the process
E = m c²
E = 0.00723 × (3× 10⁸)²
E = 6.50 × 10¹⁴ J
